SPECIFICATION forming part of Letters Patent No. 691,845, dated January 28, 1902. Application filed April 2, 1901. Serial No. 54,075. (No model.)

To ctZZ whom it mag concern:

Be it known that I, SYLVESTER DAVIS, a citizen of the United States, residing at Ha warden, in the county of Sioux and State of Iowa, have invented a new and useful Axle- Spindle Cutter, of which the following is a specification.

This invention relates to axle-spindle cutters, and has for its object to provide an im'- proved device of this character which is adjustable .to cut and trim theshoulders of a spindle and to cut screw-threads upon the reduced outer terminal of the spindle. It is, furthermore, designed to facilitate theapplt cation and removal of the device and to provide for the convenient manipulation thereof when applied to an axle-spindle.

With these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings,and particularly pointed out "in the appended claims, it being u n derstood that changes in the form, proportion,

size, and minor details may be made within,

the scope of the claims without departing from the spirit or sacrificing any of the advantages of the invention;

In the drawings,'Figu're'l'is a perspective view of an axle-spindle cutter constructed in;

accordance with the present invention. Fig.

2 is a central sectional view thereof, taken in 1 the plane of the cutting-knives and show-ing the device applied to out the outer end of a spindle. Fig. 3 is a similar view showing the device applied to trim the inner shoulder of a spindle. Fig.4 is a similar sectional view showing the device arranged and applied for threading the reduced outer extremity of a spindle. Fig. 5 is a detail sectional view taken atsubstantially right angles to Fig. 4.

Like characters of reference designate corresponding parts in all of the figures of the drawings.

As best indicated in Fig. 1 of the drawings,

displacement thereof.

in g-spindle 8 passes through the adjacent ter- 4, which extends into the respective opposite I face of the body and lying transversely across the groove'and the knife to prevent accidental A rotatable adj ustminal sl1oul der-5,'l1aving its inner end portion screw-threaded and taking into a corre spondingly screw-threaded opening in the outer end of the knife, there being a handwheel 9 upon the outer end of-the spindle for convenience in turning the same to slide the knife endwise in opposite directions for adjusting the inner cutting end to the spindle to be out. w

The intermediate arm portion 10(bestshown in Figs. 1 and 5) is provided in its outer face with a longitudinal groove for the reception of theinner end of a crank-handle 11, the inner extremity of which takes under a crossbar 12, that extends transversely across the grooved portion of the arm, and there being a removable headed pin 13, that fits in corresponding perforations in the crank-handle and the arm,-whereby the hanle is held against I endwise rlisplacementand also againstlateral tiltin At the back of the body there is'provided a spindle-receiving sleeve formed in longitudinally-adjust-able sections 14 and 15,0f which the inner section has its inner end fitted F0?- tatably within the opening in the body andagainst the inner marginal flange 3, there being an outer marginal groove 16 for the reception of removable projections or fingers 17,

secured to the back of the body, whereby the sleeve or cylindrical tube is held against endwise displacement and is rendered rotatable within the opening in the body. The outer the inward mutual movements of the sections. The inner diameters of both sleeve-sections are the same for the greater lengths thereof, the outer end portions being enlarged or socketed to form the respective inner marginal shoulders 20 and 21 for the support ofthe respective rings or washers 22 and 23, of which the outer washer 23 has the greater internal diameter, both washers being of the same thickness and the same external diameter, so as to be interchangeable,as will be hereinafter described, so as to form reversely-adjustable bearing portions constructed to snugly embrace the part to be cut. The outer sleevesection is provided with two sets of set-screws, of which the intermediate set 2% (shown in Figs. 2 and 3) pierce the intermediate thickened portion of the sleeve-section and bear against the axle-spindle, that passes through the sleeve, while the terminal set 25 (best shown in Fig. 4) pierce the outer section and bear against the inner section, so as to interlock the two sections against independent movement and also to afford means for adjusting the sleeve-sections longitudinally.

In using the device to cut or trim the outer end of an axle spindle, as shown in Fig. 2 of the drawings, the spindle-receiving sleeve is slid endwise upon a spindle 26 until the ring or washer 23 binds upon the spindle and stops the inward movement of the device, after which the sectional sleeve is adjusted longitudinally, so that the knives are in position to cut or trim the outer end of the spindle, and then the crank-handle is operated to rotate the body of the device upon the sleeve, which is rigidly secured to the spindle by means of the set-screws 24, whereby the knives are carried around in the path of a circle to cut the spindle. As the spindle is tapered outwardly the sleeve will loosely fit the same, and therefore the washers of different internal diameters have been provided to fit snugly the spindle, and thereby prevent looseness or rocking of the device during the rotation of the body portion thereof. To trim the inner shoulder of the spindle, as shownin Fig. 3, the device is removed and reversed, the spindle being received first through the opening in the body and then through the sleeve, so as to bring the knivesupto theinnershoulder,itbeingunderstood that the knives are first interchanged, so as to be reversed, the washers also being interchanged and the crank-handle reversed, so that it may now come upon the sleeve side of the device for convenience in operation. For cutting screw-threads upon the reduced outer extremity of the spindle the device is applied as shown in Fig. 4 and in the manner described for the first application, except that the set-screws 25 are loosened to permit of the body and the inner sleeve-section being pushed inwardly to accommodate the body to the inward lead of the threads to be out. To feed the device inwardly, so as to cause the knives to cut screw-threads, there-is provided a nut-holder 27, having a central polygonal open-ended socket for the reception of a nut 28, (shown in Fig. 4-,) and which fits the screw-threads already upon the outer extremity of the spindle. The inner end of the holder is provided with a base projection 29 (shown in Fig. 5) and which is designed to take into the inner end of the groove in the body portion 10 and under the cross-bar 12, the opposite end of the holder being provided with a dovetailed foot 30, that fits into a corresponding dovetailed groove in the middle portion of the outer face of the body, whereby the holder is secured in place with its polygonal socket centered axially with respect to the spindle. As the device is rotated by manipulation of the crank-handle the nut turns therewith upon the screw-threads already upon the spindle, thereby feeding the device inwardly and causing'the knives to cut inwardly-leading screw-threads upon the spindle. It will be understood that the nutholder is used only when screw-threads are being out upon the spindle.
